Can you believe they've come this far by now? Once known as OpenBeOS, Haiku today announced the release of the fourth alpha for Haiku R1. It seems like only yesterday when BeOS died and OpenBeOS rose form its ashes, generating a new hope among the legions of avid BeOS fans. Now, almost twelve years later, we've hit the fourth alpha.

First they have to make gcc 4.7 available in the system as default compiler.

Qt5 is more C++11 friendly.

the default one (that you can set with setgcc gcc4) is 4.6.3 right now, if i remember correctly. Upgrading to 4.7 is not a big deal. The haiku devs dont like to upgrade the compile short time before the release, but I'm quite sure, it wont take much time, and gcc will be updated in the nightlies to 4.7.x
That's what i like at haiku, that fact, that they have a quite up-to-date compiler. You can even use clang if you like.

I'm currently working on this a bit right now. As things stand, the Haiku sources need some changes here and there to compile with GCC 4.7.2. I'll be sure to get them all sorted out before I commit the updated buildtools. That said, the jump to GCC 4.7.2 isn't quite as trivial as I initially expected, so it may take me some time to make sure I get it into a working state that can be committed.
